Just bought a slightly used DCAEK from a forum member and got to installing it today. Took me over an hour to get everything cleaned up, installed and reassembled. The hardest part is installing the USB (Ultimate Striker Block) which requires the removal of the rear sight.

Here’s the kit all laid out and ready to go :

Initial trigger pull weight is 5.5lbs

After installing, cleaning and polishing a little, here’s the new trigger weight:

Not only did it reduce the trigger weight a little, it smoothened out the entire action and lights up the reset. Now it feels like a smooth DA trigger pull, light break and noticeable reset. Not as much as a RAM (Reset Assist Mechanism) would, but good enough.
